As I was reading this, getting on board with the idea, I completely forgot about the Striker until someone mentioned it.

This seems like a totally unnecessary addition. You've got the Saint, which for me is a barely overstable control driver, the Striker which is a stable control driver, the Vision which is a longer River with more turn AND fade, and the River which is the dead on/understable line shaper. I just don't see a fit in there. I already sold my Striker cause it felt completely unnecessary with the Saint/Vision/River line, and I hardly throw the Vision as it is.

I recall somewhat recently they "reworked" the Vision, and pissed off some people who loved that disc. I have a first run, and have never seen or thrown another to know what they became. Any chance they intentionally reworked the Vision to basically replace it with the same disc in the Fury? New disc = more money than trying to sell more Visions (which frankly, nobody seems to throw or talk about anyway.)
